Hey all, On Mac with Apple clang version 13.1.6 __ARM_NEON__ is already defined and will fire a macro redefined error during build. Platform.h: 602 below. Before suggesting a fix this code has been tested on non-Mac ARM builds only?
#elif (defined(_M_ARM64) || defined (__aarch64__) || defined(__aarch64)) info[0] = 0; info[1] = 0; info[2] = 0; info[3] = 0; #define __ARM_NEON__ #else info[0] = 0; info[1] = 0; info[2] = 0; info[3] = 0; #endif Stupid idea to simply change the definition to OIIO_NEON and change the use of the macro across oiio, simd.h. mikaelsundell@Mikaels-iMac-M1 OpenImageIO % grep -Rn __ARM_NEON__ ./platform.h:602: #define __ARM_NEON__ ./simd.h:84:#elif defined(__GNUC__) && defined(__ARM_NEON__) ./simd.h:214:#if defined(__ARM_NEON__) && !defined(OIIO_NO_NEON) Will submit a PR just want to make sure I don't introduce new problems, I'm a Mac-only user these days :-) Mikael
